Abstract：Objective To improve the clinical diagnostic rate of patients with heart failure ,through the retrospective analysis of their lung CT imaging features .Methods 80 patients with clinically diagnosed heart failure in our hospital from January 2015 to May 2016 were divided into acute heart failure group (37 cases) and chronic heart failure group (43 cases) according to the onset time ,speed and severity of heart failure .The clinical and CT imaging data of 80 patients with heart failure were analyzed , and the lung CT imaging features of two groups were compared and analyzed .Results The lung CT imaging features in patients with acute heart failure was characterized by pulmonary alveolar pulmonary edema .The patchy and shadow density increase were present in both lung field , and their inner zone could be found visible bronchial inflation sign .A few cases can appear "butterfly wing", while, most of the cases performanced as wide solid lesion shadow in double lung for patients with advanced stage .The lung CT imaging features in patients with chronic heart failure were characterized by pulmonary interstitial edema ,which showed interlobular septal and bronchial wall thickening , bronchial vascular bundle and hilar fuzzy and thickening and the ground -glass o-pacity.The increase of heart shape (49/80), a small amount of pericardial effusion (47/80) and pleural effusion (41/80) were appearanced in the majority patients in both groups .The pleural effusion was bilateral and the right amount was more than the left . Conclusion Lung CT examination can show the imaging performance characteristics in patients with acute and chronic heart fail -ure, which can provid strong and reliable basis for clinical diagnosis and treatment of acute and chronic heart failure .
